chapter 4 histology lab quiz

The four main types of tissues

Epithelial

connective

Muscle

Nervous

Two ways to classify Epithelial tissues

1. By the NUMBER of LAYERS simple, stratified, pseudostratified

2. By the SHAPE of the cell squamous, Cuboidal, Columnar

Simple squamous

Structure: flat thin single-layer cell

Function: allows Diffusion and filtration

Location: alveoli of the lungs (air sacs of the lungs)

Simple cuboidal

Structure: cube-shaped cell

Function: Absorption and secretion

Location: lining of kidney tubules

Simple columnar

Structure: Tall column like cells

function: Absorption, secretion, and some protection

Location: Lining of digestive tract ( stomach and intestines)

Ciliated Pseudostratified columnar

Structure: looks like multiple layers but its just ONE layer in contact with the basement membrane

Function: Moves mucus

Location: the Trachea and bronchi

Transitional

location: Bladder and urinary tract

Rest: cuboidal stretched: squamous
